If you like programming you cannot miss this post because we bring you the best pdf tutorials about Ruby in English , completely free.
Ruby is a programming language launched in 1995 by Yukihiro Matsumoto and characterized by being interpreted, object-oriented, reflective, cross-platform, open source and according to many developers: very simple and fun, the latter, by the way, was the idea of its author when designing the language: he wanted to have fun while programming .
Matsumoto took the best of his favorite programming languages: PERL, ADA, SMALLTALK, EIFFEL, and LISP, to create a powerful object-oriented language that was one step ahead of others and easy to learn by combining syntax from other technologies.
Being an object-oriented language, in Ruby anything can be an object, that is, they are instances of classes that will be manipulated as such. In addition, it incorporates all the concepts of OOP : methods, messages, inheritance, polymorphism, abstraction, classes and of course, objects.
Therefore, if you know a language like C ++, facing Ruby will not be a big problem. However, you have some differences with other languages of this type, for example the fact that the variables do not need to be declared.
As we already mentioned, another of its characteristics is that it is an interpreted language, which indicates that the Ruby interpreter evaluates the code and translates it into machine language, without the need to go through a compilation process as if it occurs in other languages.
What can a developer do with Ruby? The options are multiple and among them are creating commercial applications, distributed applications and web applications, accessing databases, processing and transforming XML code, among others.
All this wide range of possibilities, added to the ease and flexibility of Ruby, in addition to the creation of the Ruby on Rails framework, made many developers migrate from PHP and ASP to this powerful object-oriented language.
Although we have been saying that it is an object-oriented language, the truth is that Ruby is multiparadigm , you will see that it allows, in addition to OOP; procedural programming and functional programming. So without a doubt we are facing one of the most complete programming languages on the market.
The syntax of Ruby is similar to Perl or Python , so if you already handle these languages do not have to devote much time to learn it , but if you know nothing of these languages, do not worry, as we have said, Ruby's very easy and you can learn it quickly.
To learn Ruby you can sign up for an online or face-to-face course in which to follow a syllabus and carry out evaluation activities, or if you are self-taught and prefer to learn by yourself and at your own pace, nothing better than downloading the Ruby tutorials in pdf than we collect for you and that we leave you in this entry below.
We hope you enjoy them and they are useful to you 🙂
The Ruby language
We begin the list of pdf tutorials on Ruby in English, with this tutorial written by RedUSERS that serves as an introduction to Ruby and that lays the theoretical foundations for learning the language.
Its 26 pages are dedicated to describing the language in its entirety but before this it focuses on clarifying important programming concepts such as what an algorithm is. A term that you need to know to learn to program in any language.
However, not everything is theory, because in the final sections of the tutorial you will learn how to install Ruby on Windows and Linux and you will even create your first program: the famous Hello World .
For those who don't know anything about Ruby, this is an essential tutorial .
